Example Embodiment

[0032] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0033] Such as Figure 1 to Figure 3 As shown, a distributed photovoltaic power generation anti-theft monitoring method based on intelligent algorithms is characterized by including the following steps:

[0034] Step 1: Establish a distributed photovoltaic power generation database. The database information includes historical weather data of photovoltaic power plants and the same period photovoltaic power data. The sample data of the database is classified according to four weather conditions: sunny, cloudy, cloudy, and rainy. For training samples and test samples, the training samples and test samples cover the above four types of weather at the same time, and the proportions of training samples...

Abstract

The invention discloses an intelligent algorithm based electricity-larceny-preventive monitoring method for distributed type photovoltaic power generation. The method is characterized by including step 1, creating a distributed type photovoltaic power generation database, wherein database information includes historical meteorological data of a photovoltaic power station and photovoltaic power generation power data in the corresponding period; step 2, taking the meteorological data as input, taking photovoltaic power generation power values as output, and creating an electricity-larceny prevention model according to an intelligent algorithm; step 3, predicting photovoltaic power by the aid of the electricity-larceny prevention model, and calculating theoretical power generation quantity of the photovoltaic power station by the aid of a calculation model of the theoretical power generation quantity of the photovoltaic power station; step 4, inputting collected real-time power generation quantity of the photovoltaic power station and the theoretical power generation quantity of the photovoltaic power station into a power quantity abnormity judgment module to acquire an power generation electricity-larceny suspicion judgment result of the photovoltaic power station. The intelligent algorithm based electricity-larceny-preventive monitoring method has the advantages that photovoltaic power quantity abnormity judgment accuracy is high, electricity-larceny suspicion coefficients are given, auditing work efficiency is improved, and the basis is provided for effective monitoring of distributed type photovoltaic power generation.

Description

technical field [0001] The invention relates to a distributed photovoltaic power generation anti-stealing monitoring method based on an intelligent algorithm, and belongs to the technical field of photovoltaic power generation and its anti-stealing technology. Background technique [0002] At present, there is no effective prevention method against distributed photovoltaic power theft in China. However, in recent years, the new energy power generation industry has continued to rise. Based on the special power generation method and subsidy policy of distributed photovoltaic power generation, many new methods of power theft have also been born. Higher requirements are put forward for the anti-stealing work of power supply enterprises. Unlike traditional power users who steal electricity and measure less electricity consumption, the purpose of distributed photovoltaic power generation stealing electricity is to measure more photovoltaic on-grid electricity in order to obtain ad...
